Function: calc[EpiTrochoid] - animation of an  epitrochoid 

Calling Sequence:  

EpiTrochoid()
EpiTrochoidComp (a, b, c, N, n, , ) 

Parameters:  

-   numbers  

N - number of  

-   number of frames
, -   names 

Description: 

• EpiTrochoid  animates the epitrochoid traced by a point on a spoke of a wheel of radius as it rolls outside a circle of radius . The distance of from the center of the rolling wheel is c. The parametric equations are

,  

• EpiTrochoidComp compares in an array two different ways of constructing an epitrochoid. Typing and   return the two plots separately
